in Firefox, popup crossriderMain() only called once

Edit Subject

I've been working with popups for several days now, and this morning observing some new behavior, only in Firefox.

The popup's "crossriderMain()" function is only being called when I first bring up the popup. On subsequent times bringing up the popup, all the HTML shown is the same as the first time, and no javascript is being called (e.g. crossriderMain is not called again).

This is different from behavior I was seeing over the last few days, and is also contrary to this paragraph in the docs:

Code run in this scope is loaded and run afresh every time the popup is opened. Hence, each time the popup code is run, all variables, listeners, etc are not available from the previous run. If you need to retain information between popup runs, save them to the local database using appAPI.db.

Again, this is only on Firefox. Did something change here recently? I depend upon crossriderMain to initialize the content of the popup based upon some current values in the DB.

Some other oddness going on in debug mode in Firefox -- the popup code ALSO is not refreshed when, in Crossrider's debug tab, I click "Reload plugins" and "Reload Background code". I'm having to disable and re-enable the whole plugin (using the Firefox addons tab), for changes to take effect in the popup code. Perhaps these are both related to one same thing, somewhere...

It's quite easy to recreate this. Just create an extension with a popup as follows:

background.js:



			appAPI.browserAction.setPopup({

				resourcePath: 'popup.html',

				height: 100,

				width: 350

			});

popup.html:



<html>

	<head>

		<script type="text/javascript">

			function crossriderMain(jQuery) {

				alert("popup menu initialized");

			}

                </script>

        </head>

<body>...</body>

</html>

In Chrome you'll see the alert() every time you click the button. In Firefox, you'll only see it the first time you click the button.

I actually think there are a few weird things going on with Firefox lately. Debug mode no longer seems to work for me if I merely "Reload Background" and Reload Plugin". I have to clear my browser history (cache) every time I make a code change, to get things to reload. This seems like recent behavior, and maybe it's due to some Firefox update.

Hello.

We have this issue too. In FF, when the popup has been opened once, it's never loaded again.

We're monitoring the changelog but the log for the latest FF changes (September 2nd) is pretty vague: "General updates & improvements"
Should this issue be fixed now?

Regards,

Laurent

Laurent,

We use setInterval() inside of popup.js to check for updates to the DB every 2 seconds, and if updated, then also update the html visible in the popup. Background.js does not communicate directly with popup.js anymore, it uses the DB to send it commands. This seems to work for us.

Hi,

setTimeout is indeed fine to re-render the popup HTML. But as we are calling a web service while rendering, is there a way to determine when the popup is open/visible (so that we could avoid unecessary rendering) ?

Thx

It's possible you could use jQuery .is(':visible'), but I haven't tried it.
